摘要:
A process for the production of pourable and free flowing granules of materials or mixtures thereof which are suitable for use as wetting agents, detergents or cleaning products wherein an aqueous solution or suspension of the wetting agents, detergents or cleaning products is dried using a hot gas stream of superheated steam. Drying is terminated before the granules are damaged by heat, and the hot gas stream is freed from entrained particles of the materials by means of filters.
摘要:
A process for preparing a high-density granular detergent product by dry neutralizing alkylbenzene sulfonic acid with a particulate mixture of a water-soluble alkaline inorganic material, for example, sodium carbonate, and a hydratable inorganic detergent builder in an apparatus which provides both mixing and shearing of the particulate mixture, e.g. a V-Blender, thereby forming the granular detergent product. The process includes the addition of particles of pH sensitive detergent surfactant, such as alkyl sulfate, into the particulate mixture prior to the addition of the alkylbenzene sulfonic acid. The high-density product has good product homogeneity and surfactant solubility, and essentially no reversion of the alkyl sulfate to the corresponding fatty alcohol due to acid-catalyzed hydrolysis. Other pH sensitive detergent surfactants include alpha-sulfonated fatty acid alkyl ester and polyhydroxy fatty acid amides.
摘要:
A process for the production of pourable, free-flowing granules which are suitable for use as wetting agents, detergents or cleaning products from aqueous solutions or suspensions of such materials in a fluidized-bed spray granulation apparatus employing a hot fluidizing gas. The aqueous selections or suspensions are dried with superheated steam as the fluidizing and drying gas wherein the drying step is carried out in a closed-loop system comprising a steam circuit from which the water evaporated from the aqueous solutions or suspensions of starting materials is removed as a partial stream and the thermal energy released is returned to the steam circuit. The granules are discharged from the granulation apparatus before they can be damaged by heat.
摘要:
The present invention relates to a process for making a free flowing granular detergent comprising: conditioning of an aqueous surfactant paste having a detergency activity of at least 40%; rapidly forming a uniform stiff paste from said mix at a paste temperature of from 20.degree. to 90.degree. C.; granulating said paste upon mixing with a dry detergent powder.
摘要:
A process for preparing a concentrated detergent composition useful in automatic machine dishwashers comprising preparing a dry mixture of a thickening polymer and a sodium trimetaphosphate builder, then adding the dry blend to water and subsequently adding a potassium hydroxide base to form a homogeneous solution. Sodium silicate and optional ingredients are then added to the process. Compositions resulting from the process contain a K+/Na+ weight ratio of greater than about 0.5 to about 1 and a viscosity of from 1,800 to about 3,500 cps.

摘要:
The alkylsulphate pastes disclosed can be prepared by sulphonating mixtures containing a)50-90% by weight of at least one aliphatic primary alcohol with 6-22 carbon atoms and b)1-50% by weight of at least one unsaturated fatty acid glyceride ester derived from fatty acids having 16-22 carbon atoms and having one, two or three double bonds, with gaseous sulphur trioxide and subsequently neutralizing and hydrolysing the reaction products with aqueous bases in such a way that pastes with solids contents of 30-80% by weight are obtained.
摘要:
A process is disclosed for making substantially solvent free quaternary ammonium compounds using fatty acids, amines and quaternizing agents without side reactions that would produce esters of fatty acids. A relatively small amount of a water-alcohol solvent is used in the quaternizing reaction after which a fatty acid is added and the solvent removed by sparging and/or vacuum.
摘要:
Novel particulate blends of soap and liquid nonionic surfactants and a method for preparing same, is disclosed. The new method includes the combination of an appropriate fatty acid with the liquid nonionic surfactant before saponification of the acid. The novel particulate blends are dry, non-tacky and free flowing and are suitable for post addition to spray dried detergent powders or for use by themselves or with builders as final detergent formulations.
摘要:
A METHOD OF PRODUCING AGGLOMERATES OF DRY DETERGENT INGREDIENTS BY CHARGING PARTICULATE DETERGENT INGREDIENTS INTO A AGGLOMERATION ZONE AND MAINTAINING A CONTINUOUSLY FALLING CURTAIN OF SAID INGREDIENTS IN SAID ZONE, CONTACTING SAID PARTICULATE MATERIAL IN SAID FALLING CURTAIN WITH A SODIUM SALT OF ALKYL ARYL SULFONIC ACID TO AGGLOMERATE SAID PARTICULATE MATERIAL, MAINTAINING A TUMBLING BED OF AGGLOMERATING INGREDIENTS AT THE BASE OF SAID FALLING CURTAIN AND WITHDRAWING AGGLOMERATED MATERIAL FROM SAID AGGLOMERATION ZONE, SAID SODIUM SALT OF ALKYL ARYL SULFONIC ACID BEING PREPARED IN SITU BY MERGING SPRAYS OF LIQUID CAUSTIC SODA AND ALKYL SULFONIC ACID.
